    • 2:00-2:15 PM Chairman’s Opening Remarks and Announcements
    • 2:15-2:45 PM “Voids in Cables – some simple points to remember when gas discharge occurs” by Dr. Jim Guo, UL Solutions
      • This presentation does not consider detection, location, or characteristics of partial discharge; it focuses on the basic principles of the gas discharge within a void in a power cable. It starts with the simulation and the calculation of the electric field in the void and the field distortion in the cable insulation, which investigates how the physical parameters of a void and cable construction affect the gas discharge within the cavity. The discharge magnitude is estimated as a function of void shape, orientation, size, position, gas pressure, as well as cable conductor size and insulation thickness.  The gas discharge inception time is also described in terms of void size and test voltage. This work establishes a basic framework to understand the reaction of void-type defects to the applied electric field with various cable constructions.

    • 3:30-4:00 PM “Laser Printable Materials for Wire & Cable Applications: A Technology Overview” by Paul Brigandi, Stacey Saba, Mohamed Esseghir, Yixuan Song, Dow
      • Laser printing technology is increasingly being used for marking and identifying cables, particularly in the context of evolving communication infrastructure with potential application to power cable systems. The process involves using a laser beam to etch text, symbols, or barcodes onto the outer layer of a cable jacket, creating a permanent and highly durable mark. This method of labeling offers numerous advantages over traditional methods such as inkjet, including resistance to smudging, fading, and abrasion, and the ability to print high-quality graphics and fonts. However, conventional carbon black UV stabilized jacket compounds are not inherently laser printable.
    • This presentation provides an overview of materials technologies for enabling laser printing on Wire & Cable jacket compounds. The effect of laser marking additives, resin selection, and laser printing speed on laser mark contrast were studied on selected compositions. The advantages of a laser printable formulation are demonstrated, including abrasion resistance and UV performance, while meeting the other material needs of a jacket compound. 
    • 4:00 – 4:30 PM “Commissioning Test Best Practices to Ensure 21st Century Cable System Reliability & Longevity” by Sherif Kamel, Southwire, Landry Molimbi, Prysmian and Ben Lanz, IMCORP
      • Underground cable systems offer a long-term capital solution to resiliency and can operate reliably for decades longer than 40 years if they are installed correctly and operated within their design capabilities. The vast majority of cable system failures have a origin associated with installation errors.  As utility strategic undergrounding programs grow from multi-million to multi-billion-dollar capital investments the qualified workforce is being strained. How do we maintain at least minimum performance standards while lowering costs through economies of scale and eliminate the risk of long duration
        outages?  What is the industry best practice to ensure sensitive insulation systems are installed correctly?  The authors present a brief overview of factory quality tests, the implications for proper handling and installation, field data gathered over the last two decades, and then propose how cable manufacturers’ standards can be updated to include an effective field commissioning test specification.

  • Subcommittee B – Accessories, Monday, May 1, 2023, 2:00 PM – 5:30 PM
    • 2:00 – 2:15 PM: Chairman’s opening remarks and announcements
    • 2:15 – 2:45 PM: “High Voltage Cable Repair Kit, a fast and innovative solution”, Alejandro Escobin (Pfisterer, Germany)
      • The rapid expansion of HV power networks leads to an increasing number of cables and accessories installed by different manufacturers. The administration of spare material and the engineering challenges in the event of a power failure are very costly and complex. Especially after the failure happens, problems with compatibility between the accessories and the spare cable are frequent. Normally, a customized solution is necessary to adapt the accessories to the specific requirements of the failed system which is time consuming and expensive. In this presentation, a very innovative universal cable repair solution will be presented. A modular repair kit and a predefined repair plan is the key to overcome problems independently of any manufacturer and/or cable design. The solution consists of a specific grouping of subcomponents placed into special durable boxes. In case of emergency, the subcomponents are assembled to a high voltage connector following a predefined installation plan. The use of a pluggable epoxy joint allows the connection of any type of cable to restore the power in the line in a fast and reliable way.’
    • 2:45 – 3:15 PM: “Changes in NFPA 70, US National Electrical Code and their impact on MV Cable accessories”, Paul Knapp (UL, USA)
      • The 2023 Edition of the US National Electrical Code (NEC) was published in late 2022. This new edition includes major changes in article 315 that will have an effect on the manufacturers, users and authorities having jurisdiction (AHJ’s), that install, use or inspect medium voltage cable system installations. The changes to article 315 for medium voltage cables now include medium voltage cables, joints and terminations including separable connectors, the article previously only dealt with MV cables.  The article will now require medium voltage cable systems beginning in 2026 to use listed accessories in these systems, and self-declaration will no longer be accepted by jurisdictions that will adopt the 2023 version of the NEC. This change is to correct a previous error that required cable to be listed but was not clear on whether or not accessories needed to be. The presentation will provide information on this significant change and what this means for the MV Cable users and manufacturers where the US NEC applies which includes almost all installations outside of Utility use.
    • 3:15 – 3:30 PM: Break
    • 3:30 – 4:00 PM: “Endurance of MV Joints under Laboratory Wet Ageing Environments”, Thomas Parker, JC Hernandez-Mejia, Caryn Riley, (NEETRAC, USA), and Nigel Hampton (UL Solutions, USA) .
      • The performance of underground distribution systems is based upon the initial performance of the accessories and cables from which they are constructed and the way in which they degrade when deployed. The paper will present results of five joint designs. The joints used the connectors provided in the kits by the manufacturer and were assembled according to the included instructions. Their performances were evaluated using test methodologies using modified multifactor (temperature cycling, elevated voltage, presence of external water) ageing protocols for MV cable core qualification standards that are most used in North America. The evaluation of the samples at the different aging stages is accomplished by performing High Voltage Time Test (HVTT) breakdown. Breakdown probability models are stablished for each design of joint. Comparisons between joint design performances are established and also correlated with previously known breakdown cable performance, this provides means for estimation of the compounded breakdown performance considering both joint and cable.
    • 4:00 – 4:30 PM: “Application of non-SF6 gases or gas mixtures in cable compartments of GIS and their consequences to the related high voltage cable accessories”, Rudy Bukovnik, Alexander Eigner, (TE Connectivity, USA, Germany)
      • Today alternative gases for the replacement of SF6 are gaining traction since SF6 is one of the most harmful greenhouse gases known till today. Consequently, the gas insulated switchgear (GIS) manufacturers have been developing and starting to use different alternating gases for replacing the SF6 gas. Those alternatives do have some consequences on the related components as they have different physical and chemical properties. One component which is affected by this change are the cable compartments of a GIS which represents the interface from the high-voltage power cable to the gas insulated switchgear housing. This presentation will show todays common groups of alternating gases and investigate the difference between SF6 and those gases especially in respect to their consequences to the related high voltage cable accessories.
    • 4:30 – 5:00 PM: “Qualification of 15 kV transition joint per IEEE 404 – technical considerations and experiences”, Dennis Bergsma (Lovink Enertech, Netherlands)
      • Transition joints from OF to solid dielectric cables are increasingly used in the distribution networks. This contribution presents one experience of qualifying 15 kV transition joint per the requirements of IEEE 404 standard, including comparison to applicable IEC and European standards. Special areas of interest considered thermal performance at high temperatures, selection and performance of the connectors used in the test program, and mechanical stresses and related issues with the sealing system. Some recommendations for possible modifications of the test program will be discussed in the conclusion.

    • 9:30 – 10:00 AM “339 miles of 400kV DC Cable – Construction Begins – Canada to NY” by Forest Rong, and Shane Miller of Kiewit. 
      • Construction for the Champlain Hudson Power Express (CHPE) project is set to commence APRIL 2023, marking a significant milestone for the highest operation voltage and longest submarine and underground cable project in North America. The project has been in the development for over a decade and will deliver 1,250 MW of renewable hydro power from Canada to New York over a 339 miles single submarine and underground cable circuit. The project is expected to be fully operational by spring 2026 and will save New York homes and businesses a total of 17.3 billion dollars over its 30-year lifespan. This presentation will discuss the logistics involved in constructing the terrestrial segment of the CHPE project, which spans a distance of 146 miles. The route runs through multiple RR-ROWs and DOT areas, passing through 39 different towns, villages, and cities, and involving over 95 facility owners. The presentation will cover the challenges posed by the arrival of 558 cable reels, the need to finalize 279 joint locations, the balancing of cable lengths and pulling calculations, a total of 324 Horizontal Directional Drills at 162 locations for a total of 20 miles in length, and continuous investigation on the soil TR, all while construction is starting. A comprehensive overview will be presented to cover the intricacies involved in bringing the CHPE project to fruition and the measures required to ensure its success.
    • 10:00 – 10:30 AM “Decommissioning of SCFF/LPOF Cables using Bioremediation” by Jake Gelhard, Project Engineer, EHV Power, and Guillaume Boisard, Environmental Engineer, Tibio. 
      • There tend to be very limited options when decommissioning old SCFF/LPOF cable circuits. The primary methods used by utilities in North America are removal and cap and drain. Removal of the circuits is usually expensive and can be very difficult or impossible depending on the location. Cap and drain is quick and inexpensive, but, over 50% of the oil remains within the cable which poses a significant environmental risk. There is another option available to utilities which is to decommission the cables using bioremediation. The ODB System® is designed to “clean” cables from the inside, using an innovative biotechnological approach. The bio solution is injected into the oil channels at low pressure which then permeates into the paper matrix. After the solution has been flushed through the cable, over 98% of the oil within the cable is removed. The remaining <2% of the cable oil is bound within the paper matrix and cannot be separated, ensuring the system poses no further environmental risk.
    • 10:30 -10:45 AM  BREAK
    • 10:45 – 11:15 AM  “Southern California Edison’s Integrated Wildfire Mitigation Strategy”, by Hunly Chy of SCE. 
      • The consequences of wildfire have profoundly impacted and continue to be a top safety risk for California. One of SCE’s efforts to mitigate the risk of wildfires associated with SCE equipment are through the deployment of covered conductor and targeted undergrounding.  SCE will discuss the Integrated Wildfire Mitigation Strategy (IWMS) and how it informs deployment of covered conductor or undergrounding.
    • 11:15 -11:45 AM   “SuedLink – The world’s longest 525 kV HVDC land cable system” by Mark Stemmle, NKT, Tanumay Karmokar, TenneT, and Martin Splettstößer, TransnetBW. 
      • In the frame of the German “Energiewende” (energy transition) there is an increase in integration of offshore wind energy from the north, while nuclear power plants are being decommissioned in the south. As the existing 380 kV AC transmission grid is not able to handle the resulting power transfer requirements, new HVDC transmission corridors have been identified to reinforce the transmission system. The SuedLink project is one of the first three HVDC transmission corridor projects in Germany, besides A-Nord and SuedOstLink, which are currently being implemented with underground cable systems. SuedLink consists of two 525 kV HVDC circuits mainly in the same transmission corridor from north to south. The longer circuit with about 690 km connects the converter stations in Brunsbuettel and Grossgartach, while the shorter circuit with about 540 km connects the converter stations in Wilster and Bergrheinfeld. This presentation will focus on the longer circuit of the SuedLink project, which will become the world’s longest 525 kV HVDC land cable system upon completion. Different phases of the project including system design, qualification testing, route and logistics planning, installation considerations, special crossing constructions and commissioning tests will be presented.
    • 11:45 – 12:15 AM “Root Cause Analysis of Partial Discharge Source during High Voltage Cable Commissioning” by Roberto Martinez of Doble.
      • This technical paper presents a case study of a problem encountered during the commissioning of a high-voltage cable. The cable GIS termination failed prematurely after a few years in service, and PD tests were not performed originally, only AC hipot was completed. After repairs, due to the premature failure of the termination, it was decided to perform AC hipot and PD testing during the commissioning. The cable passed the AC hipot test but failed the partial discharge (PD) tests during commissioning.  Different technologies were used to assess the PD signals and determine the origin. The PD results were used to investigate the root cause and correct the issue at one of the terminations. The subsequent PD measurements confirmed that the repairs were successful. The cable under study was a 115 kV cable, and its design and specifications are presented in detail. The case study presented in this paper highlights the importance of PD testing in high-voltage cables to ensure reliable and safe operation.

    • 9:30 AM – 10:00 AM Electrical Test Protocol for Improved Field Assessment of LV Cables in Nuclear Plants , by David Rouison | Technical Director Ph.D. P.Eng., Kinectrics Inc. – Forensics & Component Services.
      • Following the successful completion of its research aimed at investigating the use of Low Frequency Dielectric Spectroscopy (LFDS) and Polarization/Depolarization Current (PDC) testing to assess the condition of thermally aged Low Voltage Cables in Nuclear Plants EPRI initiated a second phase of this work. This recently completed research program investigated the application of these test techniques with the intent of developing a test protocol and an assessment framework that could be applied directly to field-installed cables. Additional cable insulations and designs were subjected to laboratory-accelerated thermal aging. While the focus of this study was again thermal aging, a sub-set of un-aged and thermally-aged samples were subjected to accelerated water exposure to discriminate between the effects of moisture and thermal aging related influences. The results of this research further demonstrated the applicability of LFDS and PDC techniques to evaluate LV cables, and showed that the changes in dielectric responses in the time and frequency domain caused by thermal aging were generally not adequately captured by ‘traditional’ electrical metrics such as DC Insulation Resistance or VLF (0.1Hz) Tangent Delta. Consequently, improved diagnostic metrics / indicators were proposed to assist in interpreting the LFDS and PDC data and were found to correlate well with typical material test results. The test methods were also able to identify and discriminate wet exposure effects. The outcome of this laboratory led research formed the basis for a test protocol and data evaluation methodology which was piloted at Peach Bottom Nuclear Plant. This pilot program was conducted over 6 campaigns between 2018 and 2022 and a total of 70 cables have been tested to date. These cables were of varying constructions but were primarily XLPE insulated. The test population was strategically selected to evaluate cables exposed to known environmental stressors as well as cables in benign environments to evaluate a wide range of cable environments. The advanced diagnostic metrics derived from the LFDS and PDC data were used along with the results of TDR and FDR testing to provide an overall assessment of cable insulation condition. Based on these results the cables were ranked in broad categories of “No Action Needed” (little to no observed degradation), “Investigate/Trend” (some level of degradation), and “Action Recommended” (high level of degradation). This presentation provides an overview of the recently concluded laboratory research and the findings from the field testing which together demonstrated the validity of the proposed test methodology to evaluate field-installed LV cable insulation degradation in nuclear power plants.”

    • 8:50 AM – 9:25 AM “Laboratory Study of the Impact of Repeated VLF Withstand Test and Subsequent AC Operation on Service-Aged Cables Nigel Hampton, UL Solutions, Josh Perkel, EPRI, Caryn Riley and Jean Carlos Hernandez-Mejia, Georgia Tech NEETRAC, and Jorge Altamirano, CME
      • VLF sources have proven effective for both withstand tests and diagnostic tests (partial discharge, dielectric loss) used to manage cable assets. Field studies confirm that overall VLF tests to the levels set out in IEEE 400.2 deliver practical improvements in reliability (fewer failures and longer times between failures) without initiating long-term problems. However, the field-based studies are not well-suited to investigating the impact of repeated testing, re-energization at power frequency and test parameters (voltage and time) outside the framework of IEEE 400.2. This study uniquely employed multiple long lengths (>70 m) of XLPE cables removed after more than 25 years of service to estimate the impact of a variety of VLF test parameters (1.8, 2.1 and 3.6 U0, and 15, 60 and 120 minutes), plus multiple applications of VLF Simple Withstand testing.
    • 9:25 AM – 10:00 AM “Applying Machine Learning for characterizing Partial Discharge in Underground Power Cable Systems for Predictive Maintenance – Part II”,” Ben Lanz, IMCORP, and Steffen Ziegler, Eversource Energy
      • Waveforms of partial discharge (PD) time domain signals are being characterized, utilizing a unique dataset of measurements describing conditions of underground power cable systems. Deep learning models initially presented on at ICC Spring ’22 have been further developed and evaluated for the purposes of providing a foundation for PD detection automatization and predictive maintenance.  The deep learning models presented outperformed predictions with traditional methods. In addition to classifying PD signals, the models identified source locations of the defects within a cable system through recurrent neural networks. Additional assessments included advanced data augmentation strategies and interpretability. This update will provide updates on the deep learning advancements, augmenting data sources which further translate severity into time.  The approach furthers the paradigm shift from Risk-Ranking of PD defects to Remaining Useful Life of cable assets will be discussed.

    • 1. Suncable connection between Australia and Singapore – some ampacity issues by Dr George Anders Consulting, Canada .
      • Abstract: Sun Cable’s $22 billion Australia-ASEAN Power Link project includes a 10 gigawatt solar farm and battery on a remote pastoral station, about 70 kilometers south-west of Elliott. A transmission line in the Barkly region would connect the system to Darwin and a 3,750 kilometer undersea cable would then run from Darwin Harbour to Singapore. Large portion of the 525 kV HVDC submarine cable will be floating in water since the depth of the ocean floor is too great to bury the cables.  While the calculation of the ampacities of the buried portion of the route is following well-established procedures, the evaluation of the cable rating floating in water is not well research subject.  This presentation will explain the calculation procedure that was followed for the floating power cable and will also address an issue of a partially buried cable in the silt at the sea bottom. The results of the calculations will be compared with the ampacities of the buried portion of the route.
    • 2. VLF Testing experiences on long cable systems in Western Europe by Daniel Götz, Robert Probst, Megger, Germany
      • Abstract: This contribution shows practical case studies of after-laying testing of very long MV power and heating cables. Due to renewable infrastructure there is a trend to longer lengths of MV cables, as in Europe the VLF testing frequency is standardized at 0.1Hz this can create problems with the amount of available energy. Two case studies show how these cables can be tested with VLF voltage, and what hurdles one can have. 
    • 3. Case study of the 220kV export land cable laying, on the example of the offshore wind farm Moray East project as successfully executed on the shores of Scotland by Leszek Resner, Tele-Fonika Kable, Poland
      • Abstract: The Moray East Offshore Wind Farm consists of 100 offshore wind turbines split over three circuits. The onshore part of the export cable route runs for 34 km from the landfall at Banff to the onshore substation at New Deer. Each circuit consists of three 220 kV single core cables installed in unfilled ducts. Each circuit consists of three single core cables separately ducted in a trefoil arrangement. There are 30 sections of cable connected through 29 intermediate joint bays. Tele-Fonika Kable Group has produced and deliver more than 300km of 220kV cables with construction A2XSA(FL)2Y-GC-WTC, 8km of 66kV cables and 11km of single core bonding lead cables. Cables production has started at the beginning of 2019 and the last deliveries had place in first quarter of 2020. Cable construction, including aluminum screen wires in combination with demanding Scottish landscape and COVID lockdown restrictions, made this project special and challenging in a few aspects. In April 2022 the Moray East wind farm offshore Scotland has, achieved its full contracted output of 900 MW to the UK National Transmission Grid, makes project successful.
